The morphology of the transition from flat to normal subduction in eastern central Mexico is explored using intraslab earthquakes recorded by temporary and permanent regional seismic arrays. Observations of a sharp transition in slab dip near the abrupt end of the Trans-Mexican Volcanic Belt (TMVB) suggest a possible slab tear located within the subducted South Cocos plate. The eastern lateral ...

From among the several types of slabs, there is uncertainty about most cost-effective one for structures with short, medium, and long spans. A study comparing cost solid, flat, hollow block (HB), post-tensioned (PT) slabs 4, 6, 8m spans was conducted using SAFE software. For each span length, total quantities concrete steel bars were found compared 4 slabs. Then, bars, concrete, blocks, tendons...

New European product standards now include a mandatory requirement for manufacturers to declare the temperature-dependent thermal conductivity for each insulation used in building equipments and industrial installations. For pipe insulation systems, the measurement is usually performed by a standard pipe test method, in which the value on a large temperature range is integrated to reduce temper...

The seismic performance analysis of steel–concrete composite frames involves, as known, the interaction several load-bearing components that should be properly designed, with multiple geometrical and mechanical parameters to account. Practical recommendations are given by Eurocode 8 (EC8) – Annex C for optimal detailing transverse rebars, so ensure activation conventional resisting mechanisms. ...
